STOPPER ATTACHMENT FOR INK-BOTTLES.

SPECIFICATION forming part of Letters Patent No. 552,859, dated January'7, 1896.

Application filed April 17, 1895. Serial NO. 546,003- (NO model.)

To ctZZ 1071x0722, it may concern:

Be it known that I, GUSTAVUS R. WEED, a citizen of the United. States ofAmerica, residing at Orange, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in StopperAttachments for Ink-Bottles, of which the following is a specification.

My invention consists in certain improvements upon the stopper shown inmy former patent, No. 500,982, granted to me July 1893.

In the accompanying drawings, which form apart of the specification, thefigure is acrosssection of an ink-bottle with my improved stopper, thesection being taken on a vertical plane through the middle of the bottleand stopper. The dipping-tube is shown in elevation.

The stopper is inserted in the mouth of the bottle A.

There is a round orifice cut through and centrally located in thestoppeig'so that the stopper is practically a collar or ring B,preferably of rubber. From the bottom of this collar a circular flange Bextends outwardly and upwardly. This flange bears against the neck ofthe bottle and holds the stopper in place. The stopper seals the bottleas a perforated flexible cork. Through the circular aperture in thestopper is passed an air-tube C, which is open at the bottom and top. Itis upset at the bottom so that the stopper shall be readily withdrawnwith the tube. This air-tube has a flaring top a, which is turned up toform a ring to hold the (liaphragm D. This ring is held in the fingerswhen the stopper is being inserted in the bottle. It may be called aguard and pressure ring, because it guards and holds the rim of thediaphragm and because there the stopper can be gripped without alteringits shape. The stopper is inserted and withdrawn by pushing or pullingon the air-tube held by its ring. A stop-disk F, with a round hole atits center, is slipped on the guard-ring above the stopper and bearsagainst the base of the flaring top. It prevents the stopper beingpushed too far into the bottle. The diaphragm is of flexible and elasticmaterial, preferably of rubber, and has a thickened rim 1) which fitsinto the guard-ring. The diaphragm is perforated at the center, andthrough the hole there passes a dipping-tube E. This is preferably ofglass. It is a funnel with a stem that is straight throughout part ofits length, is tapered at one end so as to reduce the size of bore, andis flared outwardly at the other end to form the mouth of the funnel.Upon the tapering end is slipped a piece of rubber tubing 6 whichextends down into the ink-well.

The peculiar advantage of a dipping-tube having a straight stone, asshown, is that it can be readily slipped up and down in the hole in thediaphragm and will stay wherever it is put, within the limit of thestraight portion of the stem.

If the stopper is inserted in a bottle with the dipping-tube in place,as is quite commonly done, the air above the ink in the bottle iscompressed and the ink will be forced up into the dipping-tube and mayspurt onto the hands. The vertical adjustment of the dipping-tube makesit easy to avoid this by pulling the tube up before attempting to insertthe stopper, and the taper of the tube aids in avoiding this and also inavoiding any spurtin g when the pen is pressed into the funnel of thedipping-tube. The straight part of the dipping-tube'is also advantageousbecause the tube will not work out when pressed by the pen, as it mightdo if tapering along its whole length; but it is not necessary to removethe stopper in order to fill the bottle. The stopper is set in placewith the stop-disk resting on the rim of the mouth of the bottle. Thedipping-tube and diaphragm can be removed and ink poured into theflaring or funnel-shaped top of the air-tube. The diaphragm is thenslipped into place and the dipping-tube inserted through the hole in thediaphragm. Adjustments for differences in height of ink in the bottleare effected with the dipping-tube.

One advantage of the construction shown in this present application overthat shown in the former patent is that the diaphragm in the presentapplication is under compression instead of being under tension, as inthe former patent. For this reason it can be removed and replaced withless wear on the dia phragm, and when in place is much less liable to bepunctured by the pen being accidentally brought in contact. In orderthat it shall stay in place and shall have the springiness necessary tooperate properly under the pressure of the pen, the diaphragm must ofcourse be made a little larger in circumference than the circumferenceof the inner wall of the pressure-ring.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. The combination of a perforated stopper provided with an air tubewith a funnelshaped top and a ring, and a diaphragm slipped within thering so that it is supported at its circumference thereby, substantiallyas described.

2. The combination of a perforated stopper provided with an air tubewith a funnelshaped top and a ring, a diaphragm slipped within the ring,so that it is supported at its circumference thereby, and a dipping tubepassing through the diaphragm, substantially as described.

The combination of a perforated stopper, an air tube passingthereilirough, and

having a flaring end, a diaphragm supported on the flaring end, adipping tube passing through the diaphragm said dipping tube having astraight stem, a flaring mouth and a tapering end, substantially asdescribed.

4. The combination of a hollow perforated stopper, an air tube passingtherethrough with a funnel-shaped top and a ring, a diaphragm supportedon the ring, and a dipping tube passing through the diaphragm andprovided with a flaring end, a stem straight in part, and a taperedbore, substantially as described.

5. A perforated elastic stopper consisting of a collar and a circularflange extending outwardly and upwardly from the bottom thereof,combined with an air tube passing through the stopper, which is flaredand provided with a ring at its upper end, substantially as described.

Signed by me, in East Orange, New Jersey, this 15th day of April, 1895.
